Chrysaora hysoscella jellyfish, also known as the compass jellyfish. It is one of the dozens of jellyfish species that have been living (and coexisting with other species) in the Greek seas for thousands of years. Contact should be avoided because it can cause severe irritation.

It is safest to not touch anything at sea that we do not know and to avoid removing anything from the seabed. With a mask and calm observation underwater, marine organisms and many species that are unknown to us can be observed and admired. 

Let’s not forget that we are guests to our seas. Knowledge about marine life makes us less vulnerable and ensures the survival of marine species. With common sense, and without panic or unnecessary fears, we can be safe. 

In the Greek seas, where there is more than 18,000 km of coastline, identifying and recording marine life is very difficult without the participation of citizens.

We thank all those who have submitted to the Archipelagos Institute and continue to send reports and photos of jellyfish outbreaks, foreign species and other interesting observations of the sea.
